Canon EF 600mm f/4 DO IS To Arrive in Late 2017 [CR2]

We’re told that the Canon EF 600mm f/4 DO IS that was shown in prototype form at Canon EXPO in September of 2015 is currently scheduled to be launched in the second half of 2017.

Along with the new DO supertelephoto, we’re told that Canon is well on its way developing updates for the other “big white” prime lenses. While optics will likely be similar, Canon is working on weight savings techniques and updated coatings and IS systems. We don’t expect to see these lenses announced in 2017, although we’re told it’s possible we may see them being tested at the 2018 Olympics in South Korea.

As with all lens announcements, take them with a grain of salt, as they do have a tendancy to be met with delays.
